[sdiy] An Improved Sine Shaper Circuit

[Ben Bradley]

That's a fascinating idea and good work, an improvement over a common
sine shaper I first saw decades ago,
First I have an observation of a 'slight' error. The + and - inputs of
the first two TL074 sections appear to be swapped.

Next, may I post this elsewhere, specifically on diyaudio.com? They
have a perennial interest in low-distortion sine wave generation,
generally lower distortion than this gives, but some there may find
this useful.
